where: exurb of cincinnati, 80% 2-lane rural roads with speed limits 35-45, 10% residential, 10% 4-lane arterial (limit 35). No shoulders or bike lanes, aside from MUPs.
when: to and from school, 4 miles each way, at 6:30am and anytime between 3pm and 7pm.
how: there's a mup adjacent to the residential road, so I ride on that. On the rural roads, I ride about 2 feet inside the white line. For the arterial, it depends on the circumstance - there's a traffic light right where the rural road transitions to the arterial.
if I come up on a red light with cars waiting, I filter past, wait for the light to change (its too busy to consider running) and go onto the sidewalk for the last .5 miles of my trip so nobody gets mad about me cutting them off. If there's a red light with no cars waiting, I go up to the light, wait for the green, and proceed 2 feet from the white line. If it's green, I just go through and stay in the road.
At stop signs, I basically just yield, of course slowing to a reasonable speed.
